WINDING MACHINE Application filed July 23, 1927, Serial No. 207,994, 1116. in Germany July 31, 1926;

This invention relates to improvements in winding machines, and more particularly to those in which the bobbins are driven through friction gearing. Machines of this kind are already known in which the bobbins are driven by'and can be disconnected from friction discs and are carried upon a pivoted lever, but no provision has been made in such known winding machines for disconnecting the drive by tipping overthe bobbin and its wharve away from the driving disc.

According to the present invention, such winding machines are so constructed that when a particular tension in the thread lying below the breaking point of the thread is reached, the bobbin with its friction disc is removed automatically from the driving friction disc by the action of the pull in the thread, so that a pivoted member carrying the bobbin is tilted over and remains in the nonworking position. For this purpose, the bobbin is carried by the pivoted member in such a manner that when the bobbin is being driven, its weight has substantially no effect upon the tension in the thread, whilst the thread is conducted on to the bobbin in afavourable direction substantially at right angles to the operative position of the-pivoted member.

The invention is illustrated diagrammatically by way of example in the accompanying drawings which show two forms of construc tion, and in which Fig. 1 is an end view of a winding machine according to one construction, and

Fig. 2 is a similar View showing a modification. 7

In both figures of the drawings, the left hand sides of the machines illustrate the bobbins in the operative positions, whilst the right hand sides show the bobbins in the inoperative positions.

I Referring to Figure 1, the thread is shown as being wound off from a swift 2 on to a bobbin 3 provided with a wharve 10 driven fric-f tionally from a friction disc 6. The rotation of the swift is controlled by a loaded bandbrake 1. The thread passes from the swift 2 over a guide member 9 and then on to the bobbin 3. This latter together with its wharve 10 is carried by a member 4 pivoted at 7 and shaped as a bell-crank lever with a pair of arms, one of which actually carries the bobbin and its wharve while the other has weights 5 which can be selected so as to have any desired value according to circumstances. In Figure 1 th1s pivot 7 is shown as being vertically under the axis of the bobbin 3 so that the weight of the bobbin is ineffective while the bobbin is being driven from the friction disc 6. In this construction, while the tension ln the thread is normal, the weights 5 mainta1n the desired-driving relationship between thewharve 10 and the friction disc 6. If, however, the thread is not for any reason delivered properly from the swift 2, the sudden increase in tension in the thread causes the bobbin to become disconnected from the frict on (1150 6 so that the drive is no longer effective unt1l the driving relation is again resumed. If the increase in tension in the thread is considerable, the pivoted member 11s turned about its pivot 7 so that a counterwelght 8 upon the arm carrying the bobbin 31s permitted to overcome the effect of the, weights 5, so that the member 4 takes up the position shown in the right hand half of Figure 1, in which position the thread is now un der no tension at all. A stop 11 may be providedto limit the movement of the member 4.

In the construction shown in Figure 2, the member 4 is provided with three arms, one of which carries the bobbin 3* and its wharve, another carries the Weights5 to obtain the driving connection between the wharve and the disc 6, While the third arm is provided with the counterweight 8 It will be seen that-in this case, the pivot 7 a is disposed vertically above the axis of the bobbin 3 instead of vertically below as in the previous example, although otherwise the action is similar. By pivoting the member 4 either vertically below or above the axis of the bobbin, neither the weight nor any increase in weight of this latter has any effect upon the tension in the. thread so that the loading of the pivoted member" may be maintained constant and so that the driving connection may be broken at any particular desired maximum tension in the thread. The winding of the thread on to the bobbin at the particular angle mentioned is also desirable in that the driving connection may be broken for quite small increases of the normal tension, whilst if the thread is allowed to run on to the bobbin at too oblique an angle, the breaking limit of the thread may be quite easily exceeded. The tension in the thread and the pressure required to maintain the driving 1 connection between? the wharveand the friction discs are dependent by friction gearing and movably mounted ona suitable support in such a manner that the weight of the bobbin is substantially without effect in the driving position, the thread being wound on to the bobbin at favourable angles to the operative position of said support so that when the tension in the thread reaches a particular value lying below its breaking point the driving connection in said friction gearing is broken.

2. A winding machine having a wharve equipped bobbin driven through said wharve by friction gearing and carried by a pivoted member in such a manner that the weight of the bobbin is substantially without effect in the driving position, the thread being wound on to the bobbin at favourable angles to the operative position of said pivoted member so that when the tension in the thread reaches a particular value lying below its breaking point the driving connection in said friction gearing is broken.

3. A winding machine having a wharve equipped bobbin driven through said wharve by friction gearing and carried by a pivoted member in such a manner that the weight of the bobbin is substantially without effect in the driving position, the thread being wound on to the bobbin at substantially right angles to the operative position of said pivoted member so that when the tension in the thread reaches a particular value lying below its breaking point the pivoted member is turned about its pivot and the driving connection in the friction gearing broken.

4. A winding machine having a wharve equipped bobbin driven through said wharve by friction gearing and carried by a pivoted member having in operative position its pivot disposed in vertical alinement with the axis of the bobbin, the thread being wound on to the 5. A winding machine having a wharve equipped bobbin driven through said wharve by friction gearing and carried by a pivoted member having in operative position its pivot disposed vertically below the axis of the bobbin, the thread being wound on to the bobbin at favourable angles to the operative position of said pivoted member so that when the tension in the thread reaches a particular value lying below its breaking point the driving connection in said friction gearing is broken.

6. A winding machine having a. wharve equipped bobbin driven through said wharve by friction gearing and carried by a pivoted member having in operative position its pivot disposed vertically above the axis of the bobbin, the thread being wound on to the bobbin at favourable angles to the operative position of said pivoted member so that when the tension in the thread reaches a particular value lying below its breaking point the driving connection in said friction gearing is broken.

7. A winding machine according to claim 1 having a loaded lever normally tending to maintain the driving connection in the friction gearing and a second lever carrying a counter weight, the latter after a rocking movement of a certain degree causing the bobbin to go instantly and remain in its position of rest.

8. A Winding machine according to claim 2 having a loaded lever normally tending to maintain the driving connection in the friction gearing and a second lever carrying a counter weight said levers being connected to said pivoted member and so balanced with respect to one another and the pivoted member with the bobbin that after a certain rocking movement the pivoted member with the bob-- bin goes instantly and remains in its position of rest.

In testimony whereof, I have signed my name to this specification this 6th day of July, 1927.
